The height is NEVER a side of a triangle unless the triangle is RIGHT. • ## a. A square whose sides have length 8 cm. • ## b. A rectangle whose length is 5 m and width is 11 m. • ## c. A triangle whose side lengths are 3 in, 4 in, and 5 in. • ## a. A square with area 256 in2. • ## b. A rectangle with area 345 ft and length 15 ft. • ## c. A triangle with area 12 mm and a base length of 6 mm. • ## Rhombus Area = ½d1d2 (d = diagonal) ## You can justify the area formula for parallelograms as follows: ## Ex 3: Find the area of parallelogram ABCD ## Ex 3: Find the area of parallelogram ABCD  ## Ex 5:The area of a trapezoid is 135 cm2, height is 9, and one bases is 11. Find the other base. ## Ex 6: Find the area of the rhombus. ## Ex 7: The area of a rhombus is 40 in2 and one of the diagonals is 8 in. Find the other diagonal.  Yüklə 1,33 Mb.
